As for installing the syrup feeder frame, i was nervous like heck and procrastinated the action until afternoon. Turned out that the bees were very tame and less than ten got lost.
First i worked a piece of scrapwood into, let's call it a feeder-entrance blocker:
First i clamped down the wood to my workbench and started to thin the bottom-part on both sides, using my hand-tool planer:
This is how it is supposed to go in to prevent any bee-spillage:
And here it is fully inserted, blocking the bees from crawling up to the center channel.
With that done, i got fully dressed, grabbed the hive tool removed the outer and the inner cover and placed the feeder frame on top of the honey super. Only a few unlucky bees flew off and started to circle the hive. Here's the frame on top of the hive:
With the frame on top and the feeder entrance sealed, no more bees could run out and i had ample time to fill up both chambers in the frame with sugar syrup. A total of 8 liters (>2Gallons) went into both chambers, that, together with the full honey super should be enough to feed a hive until late March / early April. Here are two pictures of the partially filled feeder-frame with one float installed:
I let the whole hive rest for a couple of minutes and some of the "escabees" returned, landed on the floats and began to drink syrup. Then i pulled out the entrance blocker, quickly added the inner- and the outer- cover and was done. No need to open that hive until spring. (I hope).
I haven't installed the quilt-box [yet] - the air in my garage is very dry, despite having the fodder-tower in there.
